Benefits of technology
The invention is a seat sliding apparatus that solves the problem of being unable to move the seat because of the lock lever. The apparatus includes a lower rail, an upper rail, a lock lever, a supporting bracket, an operating lever, and an urging member. The supporting bracket has a supporting wall portion that serves as a fulcrum of rotation for the operating lever. The operating lever has a slit-like holding groove that locks the urging member in place. The supporting wall portion has a molded portion that matches the width of the holding groove. The technical effect of this invention is that it allows for easy movement of the seat without being restricted by the lock lever.
Problems solved by technology
Incidentally, the vehicle seat sliding apparatuses in Japanese Patent No. 3646356, Japanese Patent No. 3449227, and Japanese Patent No. 3647502 are all configured to assemble the torsion spring to a lever (lock lever or the like) movable (rotatable) with respect to the upper rail, and hence the assembly work of the torsion spring becomes complicated.
Then, a rod-shaped or a pipe-shaped operating lever has a configuration to be connected to the lever including the torsion spring assembled thereto in a state of being engaged with the torsion spring, and hence the assembly work of the operating lever also becomes complicated.

Embodiment Construction
[0024]Referring now to the drawings, an embodiment in which the invention is embodied will be described below.
[0025]FIG. 1 is a perspective view showing a vehicle seat sliding apparatus 1 according to the embodiment which is mounted on a vehicle such as an automotive vehicle, and FIG. 2 is a lateral cross-sectional view taken along the line A-A in FIG. 1. As shown in FIG. 1, FIG. 2, and FIG. 12, a lower rail 3 is fixed to a vehicle-floor 2 in a state of extending in the fore-and-aft direction of the vehicle, and an upper rail 4 is mounted to the lower rail 3 so as to be movable relatively to the lower rail 3. A seat cushion 80 is fixed to the upper rail 4.
[0026]As shown in FIG. 2, the lower rail 3 includes a pair of side wall portions 11 extending upright from both sides thereof in terms of the widthwise direction and a bottom wall portion 12 connecting proximal ends (lower ends) of the side wall portions 11. Then, folded-back wall portions 13 which are formed to protrude inward in ...

In a vehicle seat sliding apparatus of the type wherein rotating an operating lever causes a lock lever to allow an upper rail to slide along a lower rail, the operating member is supported by a supporting bracket fixed to the upper rail to rotate about a fulcrum which is in the form of a plate of the bracket. The operating lever is provided with a slit into which a spring is fitted for being urged. The bracket also holds the spring. To avoid an engagement between the plate and the slit when the operating lever passes during an assembly of the apparatus, the plate is configured to incline relative to the slit.
Description
CROSS REFERENCE TO RELATED APPLICATION[0001]This application is based on and claims priority under 35 U.S.C. Section 119 to Japanese Patent Application No. 2009-080240 filed on Mar. 27, 2009, the entire content of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates to a vehicle seat sliding apparatus.[0004]2. Description of the Related Art[0005]In the related art, various types of vehicle seat sliding apparatuses are proposed (for example, Japanese Patent No. 3646356, Japanese Patent No. 3449227, Japanese Patent No. 3647502, JP-A-59-2938). These apparatuses each include a lower rail and an upper rail connected to the lower rail so as to be movable with respect to the lower rail. Then, a lock lever adapted to engage the lower rail and selectively restrict the movement of the upper rail with respect to the lower rail is rotatably connected to the upper rail. The upper rail is also provided with an operating le...
